That looks like a Chevy Corvair! A girlfriend of mine in high school had a maroon Corvair convertible with which she cut a memorable image tooling around with the top down and her hair flying. :-)

This was the car that Ralph Nader made infamous and that brought Nader to widespread notice in the 1960s with his book about Corvair handling problems titled, "Unsafe At Any Speed." It was a distinctive looking car, but the Nader investigation and book doomed it and it was only around from like 1960 or so until 1969. Like the VW Beetle it had a rear-mounted air cooled engine!
